Recently I made a homemade outdoor wood burning boiler system to heat our garage. I have been excited to get this put together ever since I built our wood burning pool heater earlier this spring. I realized that with the same setup I was using for the pool, I could also heat water for an indoor heat system. All I needed was some sort of indoor radiator and fan and some underground tubing to cycle the water through.
I am planning to expand my small garage wood shop this winter and did not want to have to run an electric heater all the time to heat the garage. My other options were to purchase a small propane heater, kerosene heater, or some other type of more powerful heat system but those can be expensive. So, I decided on the wood burning heater instead. In most cases people will just put the barrel stove right in the garage, and that is a very efficient way of heating. However, my insurance company would not allow any wood burning stove (especially a homemade stove) inside the home. So this is where the wood burning boiler system design works the best. Although it is not quite as efficient as having the wood burner right in the garage it works very well to heat up our small insulated garage.
Weve been running it for approximately three weeks now, and with the temperatures dropping like they have, were really happy with the results.
For information on how I built this system, watch the video below. Thanks for watching!
I built into a simple pool heater and so far it has been working great. In this video, I show the conversion process and how I am diverting the water using the existing pool pump. This is an excellent way to heat your pool for free! I have been using recycled paper logs as well as free pallet wood for fuel and a few seasoned logs to extend the burn time. I will post actual temperatures as soon as I get the thermometer installed into the diverter.
